摘　　要：为了研究一种高压静电压力旋转喷嘴的雾化特性,采用浸入法测量了该喷嘴喷雾雾滴粒径在喷嘴轴向的分布状况。试验选择了3个可变操作条件:液体压力、液体流量及静电电压情况下。试验结果表明:随着液体压力、液体流量及静电电压的增加,喷雾雾滴粒径都变小且分布都会更均匀。通过对不同条件下试验数据的分析比较,发现这3个条件对雾滴粒径分布的影响存在相关性,其中静电电压的影响相对较大。In order to study the pressure-swirl nozzle＇s atomization characteristic, the particle diameter distributions along axis of the nozzle have been measured by immerging. Three alterable experimental parameters were chosen： liquid pressure, flux and electrostatic voltage. The experimental results show that, with the increase of three parameters the diameters of the droplets will all decrease. It is found that the three parameters can influence each other on the distribution of the liquid particles and the electrostatic voltage has the biggest effect.
